WebDescription. The function ippiFFTFwd is declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).. This function performs a forward FFT on each channel of the source image ROI pSrc (pSrcDst for in-place flavors) and writes the Fourier coefficients into the corresponding channel of the destination buffer pDst (pSrcDst for in-place flavors). WebThe function flavor ippiDFTFwd_RToPack that operates on images with real data takes advantage of the symmetry property It supports processing of the 1-, 3-, and 4-channel images. that the functions withAC4descriptor do not process alpha channel.
